UNITED STATES PATENT OFFICE.

WALTEBT. GODDARD, OF VICTOR, YORK, ASSIGNOR TO LOCKE INSULTOB MAN- UFACTURING COMPANY, OF VICTOR, NEW YORK, A GOBI'OBA TION OF NEW YORK.

INSULATOR-BA SE.

Be it known that I, WALTER T. GODDARD, of Victor, in the county of Ontario and State of New York, have invented certain new and useful Improvements in Insulator Bases; and I do hereby declare the following to be a full, 'clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specifica-tion, and to the reference-numerals marked thereon.

My invention relates to insulators and particularly to that class which are employed upon the roofs of buildings or other suitable supports for carrying heavy high tension line wires and has for its object to rovide a device that will support the insuator in proper position whether or not the roof or other support is inclined from the horizontal, all as will be hereinafter described and the novel features pointed out in the claims.

'A. represents an insulator particularlyadapted for carrying heavy line wires carrying hi h tension currents and the fdrm shown is preferably made up ofa plurality" of petticoated sectionsl preferably of glazed porcelain secured to or upon porcelain tubes 3 and 4 and held together to form a solid structure by a tie rod-5 and cap or end plates 6, or otherwise. v

2 indicates the lowermost annular porcelain section tapering toward the top and connected by the means shown, or otherwise, to the sections 1; ,.The lower depending flange of the section 2 is fitted over the upper end of a hollow tapering or conical base section 7 preferably constructed of some chea ma terial notla conductor such as rein orced concrete and considerably larger at the lower than at the upper end to which the porcelain section 2 is fitted.

I The inside of the lower edge of the base section 7 is hollowed out or curved to fitover and rest upon the partly s herical or corre spondcntl curved or froun ed outer surface of the hol ow base ring or section 8 provided with the annular flan e 9 at the bottom roo orother support indicated by 10.

adapted for use upon roofs having varyin I degrees of inclination to form a water she the upper edge ofthe partly spherical flange tance from the upper edge of the base and i thus prevent sparking to the latter by reason-of any leakage. The partly spherical flange is however of suflicient height on all sides to permit use upon a level roof while the insulator proper 1s maintained in -verti-- cal position so that the petticoats thereof Wlll properly shed water and perform their functions and the range of the relative adjustments of the parts isonly limited by the height of the partly spherical portion above the flange 9. If desired, the sections 7 and 8 could be fastened together in any suitable manner after adjustment but I find in practice that this is not necessary as the weight of the parts is suflicient to maintain them in proper position.

In setting the insulators it is only neces sary to secure the base section 8 upon the roof or other support in proper position and then-set the section 7 carrying the insulator pillar upon it, adjusting the latter until it extends vertically. Itfis immaterial so far as my invention is concerned whether or not the current passes down through the column and through the central tie rod 5 or the line wires are merely attached to the upper porcelain end section.

The cooperating surfaces of the two base socket joint for universal re ative adjust ment. t

2. An insulator support or base embodying a lower section havin a rounded upper portion and an upper sectlon fitting over the latter and adjustable thereon.

. 3. In an insulator, the combination of a lower base section having an upwardly ex tending annular flange and rounded or lGi partly spherical on its exterior surface and an upper base section having its lower interior edge curved to correspond with the exterior surface of the lower section and universally adjustable thereon.

4:. In an insulator the combination of the lower hollow base section having the exteriorly rounded and upper surface, thehollow conical upper base section having the interior of its lower edge fitted to'the upper surface of the lower section and universally adjustable thereon, and an insulator column resting upon said upper section and provided with an extension passing downwardly into the base.

5 The combination with the hollow lower base section having the up er exterior spherical surface and the upper ollow base section having the lower portion fitting over and universally adjustable upon the lower section of an insulator embodying one or more petticoated insulating sections supported upon the upper edge of the up er base section and having the downward y extending portion passing into the base.
